I attempted to install Debian 9 per the instructions at https://www.digikey.com/eewiki/display/linuxonarm/STM32MP1#STM32MP1-Debian9.
It’s booting to the touchscreen, displays a login prompt, but the USB keyboard is non-responsive, and after about 10 seconds of the cursor flashing at the arm login: prompt, the board reboots. This same keyboard works fine with the Yocto Linux SD card that comes with the board.
I’ve rebuilt the image twice and gotten the same results. Debian is booting to the touchscreen regardless if I have an HDMI monitor connected or not.
I’d be happy to provide a dmesg log, if I could only log in to get one. Any ideas?
